PATENT JOHN EDMUNDS, OF WALTHAM, MASSACHUSETTS, ASSIGNOR OF ONE-HALF TOGEORGE E. JORDAN, OF SAME PLACE.

MACHINE FOR FINISHING AND PRESSING WEBS.

SPECIFICATION forming part of Letters Patent No. 614,448, dated November22, 1898.

Application filed November 1 1897. Serial No. 656,987. (No model.)

To all whom it may concern:

Be it known that I, J OHN EDMUNDS, of Waltham, county of Middlesex,State of Massachusetts, have invented an Improvement in 5 Machines forStarching, Finishing, and Press ing Webs, of which the followingdescription, in connection With the accompanying drawings, is aspecification, like letters on the drawings representing like parts.

This invention has for its object to control the position of thepressure-roll employed in machines for starchin g, coating,dyeing,printing, finishing, or pressing webs of cloth and other material,wherein it is desirable to be able to regulate the pressure of theroller on the material, said pressure in a sizing or coating machinedetermining the quantity of starch, 860., left on the goods, and in afinishing or pressing machine the extent of the pressure put onto thegoods regulates and determines the finish or appearance of the goods.

Figure 1 in perspective, broken out, represents my invention as appliedto a starching-machine, one of the machines in which it is especiallyuseful. Fig. 2 is an enlarged detail of a pressure-roller, partiallybroken out, and the means to control or regulate the position of saidroll with relation to the roll with which it cooperates. Fig. 3 is aside eleva- 0 tion of a finishing-calender, showing my invention appliedthereto; and Fig. 4 is a partial front elevation thereof.

The framework A contains suitable bearings for a shaft B, carrying aroll C, said roll 5 running, as herein shown, in a box or receptacle D,located between the uprights of the framework. The shaft B has anattached gear E, which is rotated by a pinion F, acting throughintermediate pinions G H. The pin- 0 ion F is fast on one end of thejournal or shaft J, carrying the pressure-roller K, said shaft having atits opposite end a toothed gear L, engaged by a pinion M on a suitableshaft deriving its motion from any usual fast and loose pulleys. Theshaft J is extended through boxes a, fitted to be slid vertically insuitable guideways in each side frame A.

These boxes a have attached guides or sleeves b, the latter being hereinshown as rectangular in cross-section and hollow, each guide or sleevecontaining a longitudinally-movable polygonal nut c, prevented fromrotation by the corresponding interior cross-section of the sleeve orguide. Each nut is provided with a projecting pointer d, extendedlaterally through a longitudinal slot 6 in each guide or sleeve, thepointers cooperating with suitable scales f on the sleeves, at the edgeof the opening e therein, only one scale being shown in Fig. 1, tothereby indicate the amount of pressure greater or less than that due tothe weight of the roll which is being applied at the line of contact ofthe rolls O K. Each sleeve contains below its nut a spring g and abovesaid nut a spring h, and each nut c is entered bya threaded screw shaftor rod m, so that by rotating said screw said nut may be raised orlowered by turning the screw in a direction to force the nut a down onthe spring g. The pressure of the roll K on the web lying on the roll 0may be made to exceed the pressure due to the weight of the said roll byany desired amount, and by turning the said screw in a direction toraise said nuts the pressure may be taken off of the springs g and puton the 5 springs it above said nuts, compressing them, so that they,acting through the sleeves b, will lift the said sleeves, and with themthe roll K, thus reducing the pressure on the roll K,and, if desired,lifting the roll out of contact with the roll 0, so that it may berotated above it. In this way by the use of the sleeves b, they beingconnected positively with and extended above the boxes and the twosprings in the sleeves with an intermediate nut, the nut may be adjustedto exactly position the roll 0 with relation to the roll K, that anydesired amount of starch may be left in the material. To enable boththese screws to be adjusted in unison, they have been provided withbevel-gears 'n, engaged by bevel-gears p on a common shaft 4", having asuitable hand-Wheel s.

It will be understood, therefore, in this my invention that with thepressure-roll having 9 5 its journals supported in boxes or bearings,said boxes or bearings being supported at their upper and at their lowersides by springs, the effective strength of which may be increased ordiminished at will, it is possible I00 by the adjustment of saidbearings to absolutely regulate the extent of pressure of said f I I. fI i pressure-roll against another roll with which it is to cooperate,and so also, if it be desired, the pressure-roll may be supported out ofcontact with relation to the roll with which it cooperates and not exertany pressure at all on said roll.

By the use of niyinvention I do away with the necessity of removing thepressure-roll and its opposed roll to turn off their surfaces, andthereby compensate for wear and leave truly cylindrical acting surfaces.

The pressure-roller may be of any usual or suitable construction and itmay be covered in any usual manner and by any usual substanceasindia-rubber, cloth, corn-husks, &c.or it may be a plain uncovered roll.

The Web 0 being treated as herein shown is taken from the roller p ledunder suitable stretching or smoothing bars 15, thence under the roll 0and up between it and the roll K, and thence out over a feed or take-uproll w. The shaft 1" turns in bearings a on brackets a having earsentered by bolts which sustain said brackets firmly at the upper end ofthe framework A.

In Figs. 3 and 4 I have shown my inven= tion applied to afinishing-calender, the cloth passing under a guide roll 55, around astretcher-roll B and between suitable pressure-rolls P P, thence over ameasuringroll M t0 the shell M upon which it is wound. Thelongitudinally-slotted uprights A of the frame, only one of the uprightsbeing herein shown, have secured to each a bracket A having a bearing(L42 for a crossshaft a, provitled near each end with a suitablebevel-gear a (see Fig. 4) and at one end with a hand-wheel A. Eachbevel-gear is in mesh with a bevel-gear n fast on the threaded rod orshaft m having a bearing a in the bracket A The boxes (L of the upperpressure-roll P have attached thereto the guides or sleeves b,heretofore described, which contain each the nut c, with springs g and hbelow and above it, the threaded rod 712 entering the nut to raise orlower it as before to thus vary the eifective pressure of the roll P onthe web. The shaft a is located at a convenient height for the operatorto reach to effect by its rotation the adjustment of the pressure on theweb.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s-- 1. In a machine of the class described, a roller tosustain the web to be treated, a cooperating pressure-roll, combinedwith boxes to receive the journals of said roll, said boxes having eacha connected guide or sleeve provided with a nut, a screw entering eachof said nuts, springs in each of said guides or sleeves,above and belowsaid nut respectively, and means to turn said screws to adjust the nutsto compress one or the other of said springs more or less and soregulate the pressure of said roller upon the Web-sustaining roller,substantially as described.

2. In a machine of the class described, a roller to sustain the web tobe treated,and a cooperating pressure-roll, combined with boxes toreceive the journals of said roll, said boxes having each a connectedguide or sleeve provided with a nut, one of said nuts having a pointercooperating with a scale fixed to the sleeve, a screw entering each ofsaid nuts,

, springs in each guide or sleeve above and below said nut respectively,and means to turn said screws to adjust said nuts to compress one or theother of said springs more or less and so regulate the pressure of saidroller upon the web-sustaining roller, substantially as described.

3. In a machine of the class described, a box or vat, a roller locatedtherein to immerse a web in a liquid in said box, and a cooperatingpressure-roller, combined with boxes having each a connected guide orsleeve provided with a nut, a screw entering each of said nuts, a springin said guide or sleeve above and below said nut, and means'to turn saidscrews to adjust said nuts to compress one or the other of said springsmore or less and so regulate the pressure of said roller upon theweb-sustaining roller, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOHN EDMUNDS.
